Romiplostim - injection
Romiplostim - injection
This medication is used to treat a certain blood disorder (idiopathic thrombocytopenia purpura - ITP) in which the blood does not clot properly due to a lack of platelets. Platelets are a type of blood cell needed to form blood clots and prevent bleeding. Romiplostim decreases your risk of bleeding by increasing the number of platelets. Romiplostim acts like a certain natural substance (thrombopoietin) that causes the body to produce platelets.
Read the Medication Guide provided by your pharmacist before you start using romiplostim and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
This medication is injected under the skin by a health care professional, usually once a week.
